Advantages of ceramic concrete block insulation: the multi-hole ceramic block wall insulation mixed soil life consistent with the building 1, a wide source of raw materials, waste utilization rate, low cost. Fly ash, slag, sand, aeolian sand, soil containing low amounts of powder and tailings as the main raw material (with any of them can be), local materials, waste utilization rate, low cost, big profits . 2, high technology content. One of its core technology, chemical foaming conservation into bricks. 3, the process is simple and easy to operate. Gas agents using enhancers cement, fly ash, sand and other materials polymerization, by physical aerated, the use of special equipment and molding can be, without autoclave curing. 4, less demanding production conditions. Simple shed to do workshops, open storage product, no warehouse, less demanding on the quality of workers. 5. Investment vary, flexible production. From a small amount of mold can start small investment, but also directly to mass production, both fixed site production, but also shift production. 6, broad technical purposes. Using this technique transformed mold can produce hollow blocks, insulation tiles, light wallboard, insulation board, also can be used as a lightweight cast concrete roof, wall, wall, floor heating insulation fields. By using cement, lime, fly ash, ceramic sand and water as the main raw material, the use of ambient temperature and pressure curing method, after carrying out complex than the study was based on the good results, and the incorporation of the reducing agent, gypsum and other additives, were late-stage trial, has been reinforced ceramic sand aerated concrete specimens have better performance. Through this study, the following results were obtained: 1) Through the ceramic sand aerated concrete mix to enhance research, it is known as a larger proportion of cement, ceramic sand reinforced aerated concrete strength will increase; with The amount of lime to increase the proportion of its strength decreases: With the ceramic volume ratio increases, the strength will be rapidly increased, then increased slowly, and finally does not increase, or even decreases; with the ratio of water increases, there will be a peak intensity. 2) ceramic sand aerated concrete reinforced with a reasonable ratio range: the total mass of cement as cementing material 40 to 50 percent; lime is about 10% of the total mass of cementitious materials; ash cementitious material total mass of 40 to 50 %; ceramic slurry volume ratio of 40 to 45%; water feed ratio of 0.50 to 0.55; aluminum for the pulp quality 5 ~ 6 ‰, water reducing agent 1% by mass of cement, plaster calcareous materials 2%. 3) Comparative Test blank aerated concrete specimens in an absolute dry state 14 days compressive strength of up to 3.09MPa, reinforced ceramic sand aerated concrete compressive strength test specimens were in the natural water content. 14d maximum without water reducer and gypsum case 5.7MPa, there is water reducer and gypsum in a water content of 12 to 15% intensity maximum can reach 6.7MPa, to meet the requirements of A07 grade aerated concrete. It can be seen in ceramic sand aerated concrete reinforcing both played a big role. 4) ceramic reinforced aerated concrete dry bulk density of 1113 kg / m3, the water absorption of l7.3%; ceramic sand aerated concrete specimens reinforced dry bulk density of 1025kg / m3, the water absorption of 20.8%. Ceramic reinforced aerated block is lightweight ceramic and fly ash as the main raw material, through the efficient foam, ceramic reinforced, steam curing, automatic mechanical cutting and other production process. Lightweight, high strength, thermal insulation, fire protection, sound insulation, protection and other features of the new self-insulation material. As Wall Insulation materials, especially for facades filling, high-rise buildings within the wall frame (cut) structure, but also can be used as soundproofing panels and architectural decoration materials motorway. The sintered ceramic product as aggregate and cement paste and entraining organic compound. A lightweight, high strength, thermal insulation, fire protection, sound insulation, environmental protection, low shrinkage, strong impermeability, high dimensional accuracy, aesthetically pleasing, easy to masonry veneer and so on. Products for external wall materials to meet the requirements of building energy efficiency by 50%, so that the insulation system and buildings with life; to products within the wall material, the wall thickness can be reduced, increasing the area used for construction.
